+Make a hosts file with one host (your computer) and one variable, just to test:
+
+```sh
+hosts_file=hosts
+fort="$(fortune -s | head -1)"
+cowvar=cowsays
+
+echo "[cows]
+$HOSTNAME $cowvar='${fort}'" > "${hosts_file}"
+```
+
+Now ansible should be able to show that '${cowvar}' in a debug message:
+
+```sh
+ansible -i "$hosts_file" -m debug -a "msg='{{ ${cowvar} }}'" $HOSTNAME
+```
+
+Now to convert the hosts file to yaml, because it's very fashionable:
+
+
+```sh
+yaml_hosts=hosts.yaml
+ansible-inventory -i ${hosts_file} --list -y | tee "${yaml_hosts}"
+```
+
+Now you should see where the `cowsays` variable goes.
+You can safely place your `sudo` password next to that variable goes with `ansible-vault`, which will encrypt just that string.
+
+```sh
+pass="your password"
+ansible-vault encrypt_string --name='ansible_sudo_pass' "${pass}"
+```
+
+If that works, you can add the password, but in `yaml` format.
+You can do this manually, or use `gawk` to add ten spaces in front of the lines:
+
+```sh
+pass="your password"
+ansible-vault encrypt_string --name='ansible_sudo_pass' "${pass}"  | awk '{print "          "  $0}' >> "${yaml_hosts}"
+```
+
+Now to check that the inventory file works okay:
+
+```sh
+ansible-inventory -i ${yaml_hosts} --list -y
+ansible -i "$hosts_file" -m debug -a "msg='{{ ${cowvar} }}'" $HOSTNAME
+```
+
+If that works, you can echo the debug message while becoming root.
+Just add the `-J` flag so it will ask for the password:
+
+```sh
+ansible -i "${yaml_hosts}" -m debug -a "msg='{{ ${cowvar} }}'" $HOSTNAME --become -J
+ansible -i "${yaml_hosts}" -m debug -a "msg={{ ansible_sudo_pass }}" $HOSTNAME --become -J
+```
+
+Now you can update using Ansible.
+
+For Arch Linux:
+
+```sh
+ansible -i "${yaml_hosts}" -m community.general.pacman -a 'upgrade=true update_cache=true' $HOSTNAME --become -J
+```
+
+For Debian:

+```sh

+`kubectl` provides easy high-level overviews:
+
+```sh
+kubectl config view
+kubectl cluster-info
+```
+
+Unfortunately, the documentation commands work less well.
+
+# Kube-Explain
+
+The `kubectl explain` resources cannot use tab-completion.
+But you can find the same resources listed with `api-resources`, and use a fuzzy-finder, to get the same effect.
+
+```sh
+t="$(kubectl api-resources  | fzy | gawk '{print $1}')"
+kubectl explain ${t}
+```
+
+The documentation is in a classic style, which could only be improved by deletion.
+Take this fragment from `kubectl explain namespaces`:
+
+```
+DESCRIPTION:
+    Namespace provides a scope for Names. Use of multiple namespaces is
+    optional.
+```
+
+- Sentence 1: A 'name-space' is a space for names.
+- Sentence 2: If you create a namespace, you will not receive an error due to not having a second namespace.  This is also the case for deployments, variables, and files which begin with the letter 'P', but the writer was being paid per word.
+
+Continuing...
+
+```
+  metadata	<ObjectMeta>
+    Standard object's metadata. More info:
+    https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
+```
+
+So a namespace has metadata, which has something in diamond-brackets called `ObjectMeta`.
+We should understand this as 'normal metadata for an object', and the author promises us more information.
+But only a fool would trust that link, as the author's a hack, without even the flimsy excuse of being left alone with ChatGPT (the docs existed before LLMs became uncool).
+
+Completing this morality tale, entitled '*Why Nobody Reads the Docs*', we arrive at the end of Kubernetes' namespace documentation:
+
+```
+  status	<NamespaceStatus>
+    Status describes the current status of a Namespace. More info:
+    https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
+```
+
+Of course this is wrong.
+The sentence should read:
+
+```
+'Status' describes the current status of a Namespace.

+Start the proxy:
+
+```sh
+kubectl proxy &
+```
+
+Then curl the API server:
+
+
+```sh
+curl http://localhost:8001
+```
+
+Create a token:
+
+```sh
+export TOKEN=$(kubectl create token default)
+
+kubectl create clusterrole api-access-root \
+  --verb=get --non-resource-url=/*
+
+kubectl create clusterrolebinding api-access-root \
+  --clusterrole api-access-root --serviceaccount=default:default
+
+```
+
+Retrieve the API Server endpoint:
+
+```sh
+export APISERVER=$(kubectl config view | grep https | \
+  cut -f 2- -d ":" | tr -d " ")
+```
+
+Confirm that the `APISERVER` variable stored the same IP as the Kubernetes control plane IP by issuing the following two commands and comparing their outputs:
+
+```sh
+echo $APISERVER
+
+https://192.168.99.100:8443
+
+kubectl cluster-info
+
+```
+
+We can also get the certs straight from the list in `~/.kube/config`.

+Set up a practice environment with `minikube`, using either Docker or VirtualBox.
+
+1. Install the driver (VirtualBox is a good choice).
+1. Install `minikube`.
+    * Debian requires manual installation.[^minideb]
+1. Check it works.

+The installation takes a long time.

+Record a terminal command, then press 'Control + d' to exit.
+
+```sh
+script --timing=time.log stat.txt
+ls -a
+ls -al
+stat ~/.bashrc
+^D
+```
+
+Replay the session:
+
+```sh
+scriptreplay --timing=time.log stat.txt
+```
+
+Try a bare command, without any timing:
+
+```sh
+script -c 'top | lolcat' loltop
+nl loltop
+```
+
+Has your terminal messed up?
+Is the cursor hiding?
+Reset it!
+
+```sh
+reset
+```
+If you can't see any keys, keep typing anyway: have faith in your terminal.
+
+This `loltop` file will not play properly as it has no timings file.
+But you can cheat the system and use your other timings file:
+
+```sh
+scriptreplay --timing=time.log loltop
+```
+
+This will mostly not work well, but it shows how the timing file works:
